the four DNA polymerase

DNA polymerase a

DNA Polymerase α initiates DNA replication by synthesizing short RNA-DNA primers on the lagging strand. It forms a complex with other proteins necessary for DNA primer synthesis

DNA Polymerase δ

DNA Polymerase δ primarily extends the RNA-DNA primers synthesized by Pol α during the initiation of DNA replication. It plays a key role in synthesizing the lagging strand, ensuring that Okazaki fragments are correctly assembled.

DNA Polymerase ε

DNA Polymerase ε is involved in leading strand synthesis during DNA replication. It works in association with other proteins to carry out continuous DNA synthesis on the leading strand.

DNA Polymerase β

DNA Polymerase β is mainly involved in base excision repair, not DNA replication. It plays a role in repairing damaged DNA
